Docker部署redis主从+读写分离+哨兵

Docker部署redis主从+读写分离+哨兵

 前段时间给第三方部署了redis主从+读写分离+哨兵集群环境，开发想验证程序代码的稳定性，需要在测试环境搭建一套该redis系统，便用Docker持久化部署一套即可，用完即删！

一、规划

hostname	ip	port	server
master.redis	172.18.215.10	56379、46379	redis(master)(sentinel)
slave1.redis	172.18.215.15	56379、46379	redis(slave)(sentinel)
slave2.redis	172.18.215.16	56379、46379	redis(slave)(sentinel)

[root@dev templates]# tree /data/redis_test/
/data/redis_test/
├── data
├── redis.conf
└── sentinel.conf

二、redis集群（三台服务器一样的）

redis.conf

bind 0.0.0.0
protected-mode no
port 56379
tcp-backlog 511

dbfilename dump.rdb
dir ./

stream-node-max-entries 100
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit replica 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60

aof-rewrite-incremental-fsync yes
rdb-save-incremental-fsync yes
slaveof 172.18.215.10 56379
slave-serve-stale-data yes
slave-read-only yes
#--------master.redis这台服务器不需要上面三行-------------#
min-replicas-to-write 1
min-replicas-max-lag 10

 

# docker run -d --privileged=true -p 56379:56379 -v /data/redis_test/redis.conf:/etc/redis/redis.conf -v /data/redis_test/data:/data --name redis_test redis:5.0.12 redis-server /etc/redis/redis.conf --appendonly yes

 

三、哨兵集群（三台服务器一样的）

sentinel.conf

port 46379
dir "/data"
logfile "sentinel-46379.log"
sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 172.18.215.10 56379 2
sentinel auth-pass mymaster 123456
sentinel down-after-milliseconds mymaster 10000
sentinel failover-timeout mymaster 60000

 

# docker run -d -p 46379:46379 -v /data/redis_test/sentinel.conf:/etc/redis/sentinel.conf -v /data/redis_test/data:/data --name sentinel_test redis:5.0.12 redis-sentinel /etc/redis/sentinel.conf

 

四、验证
